Best Practices

Hi all,

I have a question about UEFI deployment using Dell KACE K2000... If I reinstall a computer several times, I have multiple Windows Boot Manager and I don't know how to avoid it...

Can you help me?

Actually I have 2 preinstall tasks :

The first one to configure the BIOS in UEFI mode using CCTK:

X:\Command_Configure\AMD64\cctk.exe bootorder --activebootlist=uefi
X:\Command_Configure\AMD64\cctk.exe bootorder --disabledevice=floppy --sequence=hdd,embnic --deepsleepctrl=disable --embnic1=on --embsataraid=ahci --legacyorom=enable --wakeonlan=lanwithpxeboot

The second one to partitioning the disk:

select volume 0
remove all noerr
select disk 0
clean
convert gpt
create partition efi size=200
select partition 1
format fs=fat32 label="EFI" quick
assign letter=s
create partition msr size=128
create partition primary
select partition 3
format fs=ntfs label="SYSTEM" quick
assign letter=d
exit

I also use the following mid-installation task:

bcdboot d:\windows /s s: /f UEFI
bcdedit /store S:\efi\microsoft\boot\bcd /set {bootmgr} device partition=s:
bcdedit /store S:\efi\microsoft\boot\bcd /set {memdiag} device partition=s:
bcdedit /store S:\efi\microsoft\boot\bcd /set {default} device partition=d:
bcdedit /store S:\efi\microsoft\boot\bcd /set {default} osdevice partition=d:

Do I forget something?
